Using a multimeter in continuity mode (Beep mode), ground one probe on the battery negative or a USB shield. Tap the other probe across suspect pads. The GND pad will beep. Once you find GND, the adjacent test points are usually the data lines. The CLK is often the easiest to find as it is a longer trace leading towards the CPU.
Unscrew the logic board protective matrix and disconnect the battery immediately. Your task is to pause the video at
The phone runs on a . Unlike Qualcomm devices that have a dedicated EDL (Emergency Download) mode, MTK devices use a different protocol known as Boot-ROM (BROM) .
